Which of the following is the preferred marker for detecting acute STEMI in athletes

Ref Harrison 19 th ed pg 1594 Patients with NSTEMI have elevated biomarkers of necrosis, such as cardiac troponin I or T, which are specific, sensitive, and the preferred markers of myocardial necrosis. The MB isoform of creatine kinase (CK-MB) is a less sensitive alternative. Elevated levels of these markers distinguish patients with NSTEMI from those with UA.
